Tunable Plasmon Resonance in Ag-Au Split-Ring Resonator with Inner Metallic Cross Heterogeneous Dimer Array
The plasmon resonance behavior in Ag-Au split-ring resonator (SRR) heterogeneous dimer array has been investigated numerically by using the finite difference time domain (FDTD) method. The resonance dips were tuned with the metallic SRR dimer arrays constituted by different metals. For the Ag-Au het...

The plasmon resonance behavior in Ag-Au split-ring resonator (SRR) heterogeneous dimer array has been investigated numerically by using the finite difference time domain (FDTD) method. The resonance dips were tuned with the metallic SRR dimer arrays constituted by different metals. For the Ag-Au heterogeneous SRRs dimer array, with the arms of metallic cross lengths increasing, the resonance dips in the visible region red shifted but the locations of resonance modes in the near-infrared region kept immovability. On the contrary, the locations of resonance dips in the visible region kept immovability but the resonance modes in the near-infrared region red shifted obviously with the air cuts widths decreasing. The whole resonance dips exhibited a red-shift as the environmental dielectric constants increase. The electric and magnetic field distributions of certain resonance wavelengths were also investigated. |
